Cultivation of forage rice (Oryza sativa L.) in paddy field is considered as a promising way to enhanced livestock feed supply. Pot experiment was conducted to evaluate the effects of fermented cattle and poultry manures in different levels of N application on the growth, N uptake and biomass production of forage rice. Rice cv. Tachisuzuka, Kusanohoshi and Hinohikari were grown and treated with five levels of N: 0,7,14,21, and 28 g N m-2.  The results showed that the effects of manures on plant significantly with all levels of N application. The findings indicated that in forage rice cultivation, Tachisuzuka prospects as whole crop silage (WCS) because of its highest straw biomass production and suitable feed with WCS quality compared with Kusanohoshi and Hinohikari.  Application of 14 g N m-2 was considered effective for high production of Tachisuzuka forage rice and useful for the reduction of N loading of the environment.
